Ios 有人能帮我们解决这些Xcode错误吗?
我正在尝试为我的教堂制作一个应用程序,我正在观看一系列YT教程,但我遇到了很多错误: 欢迎来到SO:)下次请在问题中发布您的代码,您也可以嵌入您的图像文件,以帮助我们更轻松地查看您的问题 您忘记添加“:”Ios 有人能帮我们解决这些Xcode错误吗?,ios,swift,xcode,Ios,Swift,Xcode,我正在尝试为我的教堂制作一个应用程序,我正在观看一系列YT教程,但我遇到了很多错误: 欢迎来到SO:)下次请在问题中发布您的代码,您也可以嵌入您的图像文件,以帮助我们更轻松地查看您的问题 您忘记添加“:” 网站(发件人:AnyObject) 在下一行,您将“{”一行放得太远了。它需要放在if语句的末尾,而不是在UIApplication.sharedApplication之后…… 还有一些其他的标点错误 当你看到一个错误说“override只能在类中使用”时,这通常意味着你忘记了某个右括号(你忘
网站(发件人:AnyObject)
在下一行,您将“{”一行放得太远了。它需要放在if语句的末尾,而不是在UIApplication.sharedApplication之后……
还有一些其他的标点错误
当你看到一个错误说“override只能在类中使用”时,这通常意味着你忘记了某个右括号(你忘记了)。你可以选择整个程序,然后执行“编辑器->结构->重新缩进”,这将帮助你看到作用域问题在哪里(这是我修复override问题的方式)
一定要阅读并注意你的错误信息。其中一条会清楚地告诉你,你在if语句后缺少“{”,当你看到“预期表达式”时,这意味着你写的东西对Swift来说都是胡言乱语(这意味着你很可能是打字错误,或者留下了一些不完整的东西)
我继续为您编辑了您的问题,并修复了您的代码。我几乎没有使用您正在使用的任何东西(我编写了游戏),但我只是按照Xcode给我的说明(中间带点的说明告诉您如何修复它):
此外,这似乎是较旧的Swift代码,因此您会遇到错误。请尝试查找用Swift 3编写的教程(或下载较旧的Xcode)
教程很棒,但它们很少教你如何解决问题。这时你必须依赖调试器和Xcode错误。请尝试在此处搜索你的错误,如果你仍然难以解决,那么你可以随时发布一个问题:p
祝你的应用好运!Stackoverflow不是你的个人帮助台。请阅读。非常感谢!我收到了和arror,还有一个黄色错误,FIRAuth.auth一直说它已重命名为auth,但如果我使用auth.auth,它说不能对“auth”类型的可选值使用可选链接黄色错误指向顶部UIApplication.shared.openURL有一个错误,它说请使用openURL:options:completionHandler:代替,但idk这意味着什么我没有firebase,所以我无法帮助。尝试搜索答案,如果你找不到答案,然后用firebase标签发布一个新问题,这样人们可以帮助:P@PanDu嗯
